When you begin a Spotlight search, Spotlight Importer will instantly grab the top results from Google and show them right next to the files from your computer.
With one click, the result will open in your default browser. You can even choose to only search a particular website.

Note: the installer can't uninstall.
To uninstall Google Importer, open a finder window, click on your home folder (your user name) in the sidebar, then find to the following files/folders and move them to the trash:
